Very Nice Jude,
An elegant solution to a procedure I've long thought about but never tried. 1/4" Lexan might work well instead of Masonite to easily draw your proposed rout out. Great technique. Do you still need epoxy or any other re-enforcement for the insert?

Hey Al,
A few years ago, I used the following technique on a Beckstein L that I didn't want to pull all apart (see pictures below). It would work just as well for uprights if you want a real nice fit with more wood, less epoxy FWIW.
Make a masonite template of the area you want to rout out. Rout out with pattern bits of varying depths 1/2" to 1-1/2". Fill masonite with epoxy to make a form and then use the form to rout out an exact copy of your cavity. Pretty simple overall; granted, a bit more work than just gap filling with epoxy but it's satisfying and I would especially recommend for open face blocks where you need that visual appeal. Charge the same as a small grand.

Al,
Another pinblock option which the others have not mentioned yet: If the original block is still well attached to the back structure, rout out a cavity in the original block for each section of tuning pins, and inset a piece of new pinblock. Epoxy, screws, dowels, whatever makes you feel comfortable. This lets you preserve the plate/pinblock relationship, making soundboard/bridge alignment a lot less complicated, as described by Del.
